Aruncus plant named ‘Fairy Hair’

ABSTRACT

The new hybrid Aruncus plant named ‘Fairy Hair’ with finely-dissected, dark green foliage holding well into the season. Light creamy buds transition to near white flowers on airy scapes above foliage. Plant habit is finely textured, short and very compact.

Botanical denomination: Aruncus.

Cultivar designation: ‘Fairy Hair’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct plant of goat's beard. The new plant was selected from initial evaluations by the inventor at a wholesale perennial nursery in Zeeland, Mich., USA in spring of 2011 from seedlings that were sown in the fall of 2009. The female parent is an unreleased proprietary hybrid between an unnamed selection (not patented) of Aruncus aethusifolius times A. dioica and the male parent is Aruncus dioicus ‘Kneiffii’ (not patented). The new plant passed the final evaluation in spring of 2014. The new plant was selected from among many other seedlings growing at the same nursery in Zeeland, Mich. which met the rigorous criteria of excellent foliage and habit established as breeding goals. ‘Fairy Hair’ has been asexually propagated since 2014 by shoot tip tissue culture at the same nursery in Zeeland, Mich. The resultant asexually propagated plants have remained stable and exhibit the identical characteristics as the original plant.

No plants of Aruncus ‘Fairy Hair’ have been disclosed or sold, under this or any name, in this country or anywhere in the world, prior to the filing of this application, with the exception of that which may have been disclosed within one year of the filing of this application and was either derived directly or indirectly from the inventor.

BRIEF SUMMARY OF THE INVENTION

‘Fairy Hair’ differs from all other goat's beard known to the applicant. Compared with the female parent the foliage is finer dissected and the habit is shorter and more compact than that all other goat's beard known to the inventor.

The nearest known cultivar to ‘Fairy Hair’ is Aruncus ‘Misty Lace’ U.S. Plant Pat. No. 15,798. Compared with the new plant, ‘Misty Lace’ is taller and broader in habit and the foliage is less finely dissected. Compared with co-pending application Ser. No. 15/732,106 Aruncus ‘Chantilly Lace’ the new plant is smaller in habit with finer leaf texture.

Compared with the female parent, the new plant is shorter and has finer textured foliage. Compared with the male parent, the new plant is slightly shorter.

The new plant, ‘Fairy Hair’, differs from all Aruncus known to the inventor in the following combined traits:

-   -   1. The foliage is finely-dissected, tri-pinnately compound,         dark-green colored.     -   2. Flower are light creamy white on airy scapes above the plant.     -   3. Plant habit is short and very compact.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the overall appearance of ‘Fairy Hair’ including the unique traits. The plant in the photograph is of a two-year-old plant grown in a shaded trial garden at a wholesale perennial nursery in Zeeland, Mich., USA. The colors are as accurate as reasonably possible with color reproductions. Some slight variation of color may occur as a result of lighting quality, intensity, wavelength, and direction or reflection.

FIG. 1 shows the habit in spring flower together with the fine textured bipinnately compound leaves.

FIG. 2 shows a close-up of the flowers and buds.

DETAILED BOTANICAL DESCRIPTION

The following description is based on two-year-old plants growing in a double poly greenhouse with supplemental water and fertilizer at a wholesale perennial nursery in Zeeland, Mich., USA. The new plant has not been grown under all possible environments and may phenotypically appear different under different conditions such as light, temperatures, fertilizer, and water, without any difference in genotype. The color descriptions are from the 2015 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used.
